When I took possession of my 2010 Terrain in Dec, the option for the mirror to tilt when the car was in reverse actually worked. Now, it doesn't on the right side. Yes I checked the setting to turn it on. I also decided to check my mirror by trying to re-adjust it from the controls inside the car and no go. Right side won't adjust. Left side works just fine. Anyone else having this problem? TIA! Jenn
